This morning, iTunes warned me that there was a carrier update available for my iPhone. The 'more info' button opened a link that explained the process, but didn't offer any details about what the update contained, other than updates with regard to my settings for my carrier, Telus.

In the spirit of interested inquiry, I thought I'd follow in the footsteps of others, and take a peek inside the update file. I started by copying the carrier file to a temporary folder and extracting the contents:

I won't claim to understand the meaning of all those settings, but some of them seem to point to Telus supporting visual voicemail, which would be interesting. And finally, the .PNG files, once decoded from iPhone PNG format, were themselves pretty boring. Very small transparent images of the word "TELUS" in all caps; these are referenced in the .plist above as Status Bar Images.

Thanks, I was wondering what these carrier updates are all about. I didn't trust it. It's a sad state of affairs when your initial response to a software update is a fear that they are going to lessen the usability of your tech gear. Aren't I supposed to be excited when updates come out? I guess I've had too many bad experiances with microsoft. lol
